(3+2i)*(2-i)=

Solution for (3+2i)*(2-i)= equation:

Simplifying
(3 + 2i)(2 + -1i) = 0

Multiply (3 + 2i) * (2 + -1i)
(3(2 + -1i) + 2i * (2 + -1i)) = 0
((2 * 3 + -1i * 3) + 2i * (2 + -1i)) = 0
((6 + -3i) + 2i * (2 + -1i)) = 0
(6 + -3i + (2 * 2i + -1i * 2i)) = 0
(6 + -3i + (4i + -2i2)) = 0

Combine like terms: -3i + 4i = 1i
(6 + 1i + -2i2) = 0

Solving
6 + 1i + -2i2 = 0

Solving for variable 'i'.

Factor a trinomial.

-1i = -2

Divide each side by '-1'.
i = 2

Simplifying
i = 2
Subproblem 2
Set the factor '(3 + 2i)' equal to zero and attempt to solve:

Simplifying
3 + 2i = 0

Solving
3 + 2i = 0

Move all terms containing i to the left, all other terms to the right.

Add '-3' to each side of the equation.
3 + -3 + 2i = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 2i = 0 + -3
2i = 0 + -3

Combine like terms: 0 + -3 = -3
2i = -3

Divide each side by '2'.
i = -1.5

Simplifying
i = -1.5
Solution
i = {2, -1.5}
